Application filed Becemher 25, 15312. Serial No. 738,515.

To all whom it may concern: v

Be it-known that I, ()soAu bl. i ouians'r, a citizen ofthe UnitedStates, resicung'at Schenectady, county of Schenectady, State.

especially to means for removing the fuse,

which is readily attached to and detached from the same. Nith fuses,such us are hommonly used in station wiring, pole work and in subwaywork, it is frequently desirable to remove the fuse without switchingoil the current, and, when the some is used. on high tension circuits,direct contact with the shell of the fuse is liable to result in a shockto the operator. My invention provides a cheap and eifective insulatedhandgrip, which is readily secured to the fuse and is easily detachedtherefrom, whereby the fuse may he removed from the base withoutdangerto the operator.

My invention is illustrated in the ecconipenying drawings, in whichFigure 1 is a vertical sectional View of the fuse box, with the fusezindthe attached handle in elevit tion, and Fig. 2 is an end elevationof inclosed fuse and the handle therefor:

Referring to'the drawings, 1 represents the box within which the fuse ismounted, provided with a coveix 2 and with suitable openings 3 for thecables. A base i of suitable insulatingnieteriel, such as wood, issecured to the bottom of the box 1, and cont-net terminals 5 are mountedon either end of the base. The wood is preferably treated its withporufiin to improve its insulating value. An inclosed fuse comprising anelongated shell 6, the ends of which are closed by cups 7 is providedwith flattened projecting terminals 9, which are adapted to engage thestationary terminals The cups 7 are provided with the usual ventililting openings 8, at least one of which 'is located in 'elineinentwith the flattened terminal 9. The handle for the fuse which embodies myinvention comprises an insulated hand-grip 10, to the ends which aresecured similar brackets 11 by screws 12. The lower ends of thehru'ckets ere slotted at ELY and are adapted to slip over the terminals9. The brackets 11 21 336 31 provided with inwardly extending lugs i iwhich may conveniently be punched "from the metallic bracket and each ofwhiclris adapted to engage one of the openings 8 in slinement with theterminal 9,10 l openings the lugs are guided. by the slc endsof thebrackets passing over the terminals, The-brackets 11 are madesuiiiciently flexible sothat when the handle is placed in position thelugs H readily ride over the edge of the cups 7 and snap into-theopenings 8. This urrungementgives a positive action and it is quitediilicult to disengage the lugs after they once snap into the openingsin order to disengage the handle, it is only necessary to pry one of thebrackets 11 outward slightly when its lug will. he disengaged from thecorresponding openin i will be seen that the device embodying myinvention is extremely cheap, as it comprises only an insulated bar,which may conveniently be made of hard wood, preferably treated in themanner above indicated, and two brackets which may he made of steelpunchings, and that the some affords a ready means for removing the fusefrom the fuse box.

in cccorduncewith the provisions of the potent statutes, 1 havedescribed the principles of operation of my invention, together with theapparatus whichl now consider to represent the best embodiment thereof;but desire to have it understood thstthe up )erotus shown is onlyillustrative, and that he invention can he carried out by other means il'het I claim as new and desire to secure by Letters Patent oi? theUnited States, i

l. A fuse remover comprising a handle of insulstiu muterinl, and twobrackets of tending transversely therefrom, the ends of said bl'HCiKQtSbeing slotted and having inturned toward one another and adapted todetschuhly engage the ends or a fuse.

A fuse remover comprising an insulut mg handle and brackets with lugs attheir adjacent sides extending transversely from said handle, saidbrackets being resiliently flexible towzml and away from one another, sothat when the remover is applied to u fuse they will separate and allowthe lugs to ride over the ends of the fuse and then return 3, A fuseremover comprising an insulat ling handle and hru kcts extending transversely therefrom end having on their adminals and to releasably securethe-handle to the fuse.

5. In combination, a fuse base, stationary contact terminals mountedthereon, an inclosed fuse comprising a shell, perforated caps coveringthe ends of said shell and terminals projecting from said caps which areadapted to engage said stationary contact terminals, and a handle forremoving said fuse comprising an insulated hand-grip,

brackets secured thereto which are adapted to straddle said projectingterminals, and means associated ith said brackets and cooperating Withsaid ventilated openings for removably securing the handle to said fuse6. In combination, afuse base, stationary integral contacts mountedthereon an inclosed fuse comprising an elongated shell for the fusehaving caps provided with ventilating openings for closing the ends ofsaid envelop, and blade terminals on said caps adapted to engage saidstationary contacts, and a handle for removing said fuse comprising aninsulated hand-grip, spring brackets secured thereto and adapted to bereceived over said projecting blade terminals, and lugs se-. cured tosaid brackets and adapted to detachably secure said handle to said fuse.

7. at incloscd fuse'having caps provided with ventilating openings andcontact terminals projecting from the ends of said fuse,

a handle comprising an insulated hand-grip, 5

brackets projecting therefrom which are adapted to straddle saidterminals, a lug projecting from each of said brackets and adapted toengage one of the ventilating. openings in said caps whereby the handle.is adaptedto be detachably secured to said fuse.

In witness whereof, I have hereunto set my hand this 24th day ofDecember, 1912.
